Why is a focus on gender so important for interpreting the world in which we live? Sixteen world-famous scholars have been brought together to address this question from their respective fields: Political Theory, Philosophy, Medical Anthropology, Law, Geography, Islamic Studies, Cultural Studies, Philosophy of Science, Literature, Psychoanalysis, History of Art, Education and Economics. The resulting volume covers an extraordinary array of contexts, ranging from rethinking trans* bodies, to traumatized tribal communities, to sexualized violence, to assisted reproductive technologies, to the implications of epigenetics for understanding gender, and yet they are all connected by their focus on the importance of gender as a category of analysis. The publication of this volume celebrates the anniversary of the launch of the Centre for Gender Studies at the University of Cambridge, and features contributions from past and future Diane Middlebrook and Carl Djerassi Visiting Professors to the University.
